Nope, her Toxicroak gets one-shotted

"You sure you wanna go through with this Marnie?" asks Gloria, clearly worried about her friend. Marnie turns back and nods in response, feeling confident she'll win. While all of her Pokemon are resistant to Sharpedo's dark attacks, only one of them has any resistance to water: Her Toxicroak, which has Dry Skin. And Dry Skin heals when hit by rain or water attacks, plus the fact it's a fighting type, which Sharpedo is weak to, also helps.

"I'm assumin' it's a one-on-one right? Meaning we each only use one Pokemon?" Marnie asks the perverted man.

"I mean, I only have this here Sharpedo, so yes." he replies. He seems to know what she's planning and secretly prepares for it by giving Sharpedo a TR. Marnie sends out her Toxicroak, confident she will win and tells it to use Drain Punch. She expects the man to try to go for a water move thinking Toxicroak doesn't have Dry Skin.... "Go! Use Psychic Fangs!" Unfortunately for Marnie, Sharpedo outspeeds her Toxicroak and her Toxicroak goes down before it could even do anything. This gives Marnie further shock.

"But, but....there's no way you could've prepared for that before I got here!" she screams as she's in disbelief that she lost. "Bloody fucking hell mate!"

"I told ya, Marnie." Gloria retorts. Marnie proceeds to pull down her panties as the man requested, albeit, blushing redder than a Bounsweet. Gloria tries to block the view of anyone passing by but she can really only do it from one side so her efforts are futile. Marnie give the panties to the perverted man. "You can't seriously go through with him taking pictures, right?"

"A bet's a bet," Marnie replies, clearly distraught.
